Hi
I have an 08 Focus 1.6tdci which decided to die on my Thursday morning. The problem which has developed is that the engine will completely shut down under acceleration. It first happened accelerating out of a 30mph zone. There was no warning just cut off.
I turned the ignition off and on and it came back to life and allowed me to carry on under light throttle loads but would shut Down again when applying any kind of throttle.
I have plugged the car into my laptop and no faults are logged and there is no MIL light on.

Is this a known fault? Or has anyone experienced this before? Any help would be greatly appreciated

Do the filter as a first port of call. Only a cheap item. Only thing is, it sounds like a computer issue if its shutting down repeatedly. Can you get it to do it while stationary or does it only happen when moving?

I have a 2005 ex fleet focus 1.6 tdci and getting same issues as what you are describing. Did you get any resolve on yours. Diagnostics cam back with a few error codes so I changed the EGR Valve, Cam shaft sensor, Crank Shaft sensor, New fuel filter and still no joy.

Car would start fine and go about town when engine is cold but when it is up to operating temperature, rev it past 2.5k revs, engine would splutter and die out. It does not do it when cold, only when engine is warm.

It will not restart when it stalls. To get it to fire up, I have to lift the bonnet, slam it down and it will restart and continue with my journey.

I am going to replace the fuel pump relay and see if that might play a part. It seem the failure is heat related and when it gets up to temperature, the contact goes further apart hence causing it to stall.
